"There's still some inside me!?"
"...Kneading the mixture of her juices and demonic semen with her fingertips, Selene was surprised how potent the cocktail inside of her was."
Ok, for one with a fertile imagination, you had me there!
Given this is an early demo, I'll focus on what's available, considering the "early" aspect of this demo:
Art - no doubt it's looking good, and will look good. LasterK's got that nice plump aesthetic that just "pops". The chibis are cute, though their appearance in the H scenes was a surprise - I think they'll work nicely.
Sounds - Are nice. Definitely sexy stuff.
Gratuitous amount of text - It's not just text, it's sexy text! It's a visual novel, so this is a given. The more important thing is, the content and the style of the text is a turn on.
Good luck y'all! I see a nice game with good potential.
